Corrupted aesthetic

Passageway in the caves of Oregon Caves National Park. And yes, this actually is a color picture instead of B&W. Just got the Nikon D7000 this spring and I have to admit that the quality difference to my old D50 is amazing in situations like these. In my opinion the picture sharpness is still ok, when you consider that it's been taken with iso 4000 and with free hand (altough with help of my friend's shoulder).
